While at the University of Sheffield Murray did research on organic chemistry as part of a team working for the Ministry of Supply. In 1942, she joined the WRNS, rising to the rank of chief officer. She worked at Chatham barracks as chief officer directing demobilisation. A 2013 BBC report describes a secret major control bunker, later buried beneath the lawns of Magee College, Derry, Northern Ireland. From 1941 this bunker, part of Base One Europe, together with similar bunkers in Derby House, Liverpool, and Whitehall was used to control one million Allied personnel and fight the NaziU-boat threat. Murray was stationed at Base One Europe as WRNS Chief Officer and responsible for the welfare of 5,600 Wrens stationed at Londonderry.
New Hall, Cambridge
In 1946, the mistress of Girton College invited Murray to apply for a job at Cambridge. There, Murray played a major role in establishing New Hall, to address the needs of women students. She served as the first president of New Hall from its founding in 1954 until 1981. In 1975 she became Cambridge University's first female vice-chancellor for a two-year term during which time she introduced student representation on university committees, founded the Cambridge Society, and inaugurated the clinical medical school, the new music school, and West Road concert hall. In 1980, Murray published the booklet New Hall, 1954–1972: the Making of a College. In 2008, it was announced that New Hall would be renamed Murray Edwards College, in honour of the vision of its first President, Rosemary Murray, and the generosity of the Edwards family.
Town and gown
Murray served as a magistrate in Cambridge for thirty years, from 1953 to 1983, and became the first female deputy lieutenant of Cambridgeshire in 1982. She was president of the National Association of Adult Education from 1977 to 1980. She served as a member of the Committee on Higher Education in Northern Ireland chaired by Sir John Lockwood, which recommended the closure of Magee College as well as the location of Northern Ireland's 2nd University being Coleraine and led to the controversial creation of the New University of Ulster, from which she was later awarded a Doctor of Science Honorary Degree. She was a member of the Armed Forces Pay Review Body. She was a director of Midland Bank Ltd, and an independent director of The Observer.

Death
She died at the John Radcliffe Hospital in Oxford on 7 October 2004, aged 91. She had an operation to replace a heart valve, which was a dangerous procedure for a woman of 91 years. She was warned there was only a 50% chance of her survival but she went through with it anyway. After the operation, she appeared fine with cards and flowers surrounding her hospital bed and the vicar said, "I had one of those wonderful afternoons when a visit to a sick parishioner in hospital cheers you up so much, that you come home feeling a hundred time better than when you left." However two days later she seemed to become distant and the day after that, she was totally unresponsive.
